BitTorrent

BitTorrent is a peer-to-peer file sharing protocol used for distributing large amounts of data. BitTorrent is one of the most common protocols for transferring large files.

The protocol works when a file provider initially makes his/her file (or group of files) available to the network. This is called a seed and allows others, named peers, to connect and download the file. Each peer that downloads a part of the data makes it available to other peers to download. After the file is successfully downloaded by a peer, many continue to make the data available, becoming additional seeds. This distributed nature of BitTorrent leads to a viral spreading of a file throughout peers. As more peers join the swarm, the likelihood of a successful download increases. Relative to standard Internet hosting, this provides a significant reduction in the original distributor's hardware and bandwidth resource costs. It also provides redundancy against system problems and reduces dependence on the original distributor.

Programmer Bram Cohen designed the protocol in April 2001 and released a first implementation on July 2, 2001. It is now maintained by Cohen's company BitTorrent, Inc. There are numerous BitTorrent clients available for a variety of computing platforms. According to isoHunt, the total amount of shared content is currently more than 1.7 petabytes.

Downloading torrents and sharing files

Users browse the web to find a torrent of interest, download it, and open it with a BitTorrent client. The client connects to the tracker(s) specified in the torrent file, from which it receives a list of peers currently transferring pieces of the file(s) specified in the torrent. The client connects to those peers to obtain the various pieces. If the swarm contains only the initial seeder, the client connects directly to it and begins to request pieces.

Clients incorporate mechanisms to optimize their download and upload rates; for example they download pieces in a random order to increase the opportunity to exchange data, which is only possible if two peers have different pieces of the file.

The effectiveness of this data exchange depends largely on the policies that clients use to determine to whom to send data. Clients may prefer to send data to peers that send data back to them (a tit for tat scheme), which encourages fair trading. But strict policies often result in suboptimal situations, such as when newly joined peers are unable to receive any data because they don't have any pieces yet to trade themselves or when two peers with a good connection between them do not exchange data simply because neither of them takes the initiative. To counter these effects, the official BitTorrent client program uses a mechanism called "optimistic unchoking", whereby the client reserves a portion of its available bandwidth for sending pieces to random peers (not necessarily known good partners, so called preferred peers) in hopes of discovering even better partners and to ensure that newcomers get a chance to join the swarm.

How do I download files using BitTorrent?

Just like you need a URL like 'www.dodear.com' to go to a web site and download content, you need a 'torrent file', a small file that tells the BitTorrent client the necessary info to download the content you want. This is generally obtained from a torrent website. Many websites offer torrents as one method of downloading files. For example, OpenOffice.org, a free alternative to Microsoft Office, can be downloaded using BitTorrent. Other sites, like legaltorrents.com, offer torrents of all kinds of things - these sites are just repositories of torrents and usually don't actually create any of the content available. They're known as indexes or trackers - there is a subtle difference between the two.

Once you've obtained the torrent file from wherever, you simply need to import it into µTorrent. There are several ways of doing this.

• Click File then Add Torrent in µTorrent (or press CTRL+O) and locate the torrent file.
• Double-click the torrent file. (Only works if you've associated .torrent files with µTorrent - µTorrent asks you if it should do this the first time you run it. If you clicked 'No', you can do this by going to Options, then Preferences in µTorrent, then clicking Associate with .torrent files under Windows Integration.)
• (advanced) Click File then Add Torrent from URL in µTorrent (or press CTRL+U), and enter a URL from which the .torrent file can be obtained.

But before you start downloading, make sure you've followed the µTorrent Setup Guide. It doesn't take long and will help ensure that your torrent experience is faster and more consistent.
